GATE simulation of full ring for hybrid detector, plus some script to analyze data
You need to have GATE up and running, which means also ROOT and Geant4. To download (and compile the small script) execute the following commands:
git clone https://github.com/marcopizzichemi/tofRecoSimulation.git
cd tofRecoSimulation
./deploy
This will create two executables in bin/ folder
Again, you need a GATE version up and running. One combination that was found to work on lxplus is
GATE 8.1
Geant 4.10.03
ROOT 6.06.08
g++ 4.9.1
This is an extremely delicate combination...
To setup everything and compile GATE from source, do
wget http://www.opengatecollaboration.org/sites/default/files/gate_v8.1.p01.tar.gz
tar xvzf gate_v8.1.p01.tar.gz
cd gate_v8.1.p01/
mkdir build
cd build/
source /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.06.08/x86_64-slc6-gcc49-opt/root/bin/thisroot.sh
source /cvmfs/sft.cern.ch/lcg/external/gcc/4.9.1/x86_64-slc6/setup.sh
source /cvmfs/geant4.cern.ch/geant4/10.3/x86_64-slc6-gcc49-opt/bin/geant4.sh
/cvmfs/sft.cern.ch/lcg/contrib/CMake/3.8.1/Linux-x86_64/bin/cmake --verbose -DCMAKE_CXX_COMPILER=/cvmfs/sft.cern.ch/lcg/external/gcc/4.9.1/x86_64-slc6/bin/g++ -DCMAKE_C_COMPILER=/cvmfs/sft.cern.ch/lcg/external/gcc/4.9.1/x86_64-slc6/bin/gcc ../
make
Then download and compile the simulation:
git clone https://github.com/marcopizzichemi/tofRecoSimulation.git
cd tofRecoSimulation
./deploy lxplus
Just specify lxplus to deploy, so the proper source commands are executed
To run a single instance of simulation, once GATE is installed, do
time Gate -a [folder,/path/to/Gate/macros/folder][time,3][cut,10][seed,123456789][outname,output] /path/to/Gate/macros/folder/runSim.mac
where
/path/to/Gate/macros/folder -> path to the folder where runSim.mac is
time -> simulation time (setTimeStop in GATE), in seconds
cut -> production cut for gammas, electrons and positrons, in microns
seed -> seed for the random number generator
The simulation CPU time depends heavily on the combination of time and cut. For a typical (time = 3, cut = 100), CPU time is around 30 minutes. The production cut anyway has to be smaller than the relevant dimensions of the hybrid system, otherwise the results will be uncorrect.
The parameters in input allow to change the GATE simulation without changing the macro (particularly useful for submitting many jobs to condor, see later). The output of the simulation will have a name sim{cut}um.root.
To count how many fast, less fast and slow coincidences are produced, do
./path/to/bin/fastPercentage --folder ./ --input output.root --output results.txt
This will work on GATE Hits, so only real coincidences are taken into account. Results are written on terminal and in results.txt file.
To run just a visual interface, do
Gate --qt -a [folder,/path/to/Gate/macros/folder][time,3][cut,10][seed,123456789][outname,output] /path/to/Gate/macros/folder/runVis.mac
in this case, time, cut, seed and outname do not really matter.
The scripts needed for submitting in condor on lxplus are in the condor/ folder. You need to
Create a folder somewhere
copy the jobs.sub and run_script.su file there
Create 3 subdirs, err, log, out
properly set the variables in args.txt.
Each line in args.txt is a condor job. You need to specify in each line
the GATE executable file, with full path
the GATE macros folder
the simulation time (GATE time) in seconds
the production cut, in microns
the random seed
the final output file, i.e. the full path + file name where the output file will be written
Of course you need to change seed in every line, in general, and also the final output name, otherwise it will be overwritten. After this, you just need to run
condor_submit jobs.sub
